# Copy the Linux sandbox native binaries into the bin/ subfolder of codex-cli/.
#
# Usage:
#   ./scripts/install_native_deps.sh [CODEX_CLI_ROOT]
#
# Arguments
#   [CODEX_CLI_ROOT] – Optional.  If supplied, it should be the codex-cli
#                      folder that contains the package.json for @openai/codex.
#
# When no argument is given we assume the script is being run directly from a
# development checkout. In that case we install the binaries into the
# repository’s own `bin/` directory so that the CLI can run locally.
